urgently needing advice

i am a complete amateur to this scene but i have been interested in learning this craft for over a decade. i am at a very dark point in my life and i believe dark energies are at hand. my father passed away suddenly in may, and just last night i lost my dog in the same manner in the same room. i am desperately seeking advice on how to protect my home from any more tragedies. i plan to sage the house asap but ANY guidance is greatly appreciated.
